Integral Operators, Pseudodifferential Operators, and Gabor Frames

چکیده

This chapter illustrates the use of Gabor frame analysis to derive results on the spectral properties of integral and pseudodifferential operators. In particular, we obtain a sufficient condition on the kernel of an integral operator or the symbol of a pseudodifferential operator which implies that the operator is trace-class. This result significantly improves a sufficient condition due to Daubechies and Hörmander. In: Advances in Gabor Analysis, H. G. Feichtinger and T. Strohmer, eds., Birkhäuser, Boston, 2003, pp. 153--169. 7.

Representation of Fourier Integral Operators using Shearlets

Traditional methods of time-frequency and multiscale analysis, such as wavelets and Gabor frames, have been successfully employed for representing most classes of pseudodifferential operators. However these methods are not equally effective in dealing with Fourier Integral Operators in general. In this paper, we show that the shearlets, recently introduced by the authors and their collaborators...

2 00 6 Pseudodifferential Operators on Locally Compact Abelian Groups and Sjöstrand ’ s Symbol Class

We investigate pseudodifferential operators on arbitrary locally compact abelian groups. As symbol classes for the Kohn-Nirenberg calculus we introduce a version of Sjöstrand’s class. Pseudodifferential operators with such symbols form a Banach algebra that is closed under inversion. Since “hard analysis” techniques are not available on locally compact abelian groups, a new time-frequency appro...

Banach Algebras of Pseudodifferential Operators and Their Almost Diagonalization

We define new symbol classes for pseudodifferential operators and investigate their pseudodifferential calculus. The symbol classes are parametrized by commutative convolution algebras. To every solid convolution algebraA over a lattice Λ we associate a symbol class M. Then every operator with a symbol in M is almost diagonal with respect to special wave packets (coherent states or Gabor frames...

Representation and Approximation of Pseudodifferential Operators by Sums of Gabor Multipliers

We investigate a new representation of general operators by means of sums of shifted Gabor multipliers. These representations arise by studying the matrix of an operator with respect to a Gabor frame. Each shifted Gabor multiplier corresponds to a side-diagonal of this matrix. This representation is especially useful for operators whose associated matrix possesses some offdiagonal decay. In thi...
